Hi Robbie,  For the folks that now have investigated cycloexylamine
and some discovered there is a liquid form: please just stay on the
track about our discussion thread, "Player piano roll preservation
and de-acidification".

I am one of the largest dealers of used player piano rolls in the
country and I discovered this process through my bookbinder friend.
If you get the chemical in the sleeves that are protected in a glass
jar, remove a number of bags as to the amount of rolls you wish to
treat and follow the procedure I already mentioned; this process will
work just fine.

No over-thinking it out unless you are a chemist and are really just
looking for something to do.

I hope this helps everyone to know that doing these preservations
will only help to preserve their roll collections.

Sincerely Kim Bunker
